Hi,
I have these messages in my logs. I do not know how to get out this issue. Please could you help me ? I am not able to connect to the client neither with pgadmin nor psql :
2025-12-16 07:03:40.473 UTC [91205] WARNING: database "railway" has a collation version mismatch
2025-12-16 07:03:40.473 UTC [91205] DETAIL: The database was created using collation version 2.36, but the operating system provides version 2.41.
2025-12-16 07:03:40.473 UTC [91205] HINT: Rebuild all objects in this database that use the default collation and run ALTER DATABASE railway REFRESH COLLATION VERSION, or build PostgreSQL with the right library version.

After multiple attempts, I've succeeded indeed with clients and even with command line psql I wasn't able to connect to the database with this error each time :
error: connection to server at “xxxxxx.xxxx.rlwy.net” (xx.xx.xx.xxx), port xxxxxx failed: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
Then when I was connected, I ran :
ALTER DATABASE railway REFRESH COLLATION VERSION;
REINDEX DATABASE railway;
and everything worked again.

In a database client (eg, Datagrip), run the following SQL query:
ALTER DATABASE railway REFRESH COLLATION VERSION;
